Least common factor is not a mathematical term because 1 is the least, or lowest, factor of any whole number and is common to all numbers.
The Greatest Common Factor (GCF) is the largest factor common to two or more numbers. For example, 17 is the GCF of 34, 51, and 102 because it is the largest number that is a factor common to all three numbers.

What is the least common factor of 6?
There are no common factors of 6 because there cannot be common factors without two or more numbers to compare. Common factors are factors that the numbers being compared have in common. Thus, there cannot be a least common factor. In general, the least common factor of two numbers is 1.
Why do you have greatest common factor and not least common factor?
The least (meaning lowest) common factor of any set of whole numbers is always 1. The greatest common factor of any set of whole numbers will depend on the factors of the individual whole numbers in the set.
What are the common factors of 64?
A single number cannot have common factors. To be common there need to be at least two numbers.
What is the Least common denominator of 15?
The factors of 15 are 1,3,5, and 15. In order to find the least common
What are the common factors of 78?
There cannot be common factors of just one number. To be common there need to be at least two numbers.
What are the common factors of 1632?
There cannot be common factors of just one number. To be common there need to be at least two numbers.
What are the common factors of 28?
There cannot be a common factor of just one number. To be common there need to be at least two numbers.
What is the least common factor of 57?
There are not a greatest common factor, a least common factor, or common factors of a single number, such as 57, because there cannot be any form of common factor without two or more numbers to compare. Common factors are factors that the numbers being compared have in common. Thus, since there are not two or more numbers to compare, there are no common factors.
What is the least common factor of 9 and 21?
Answer: 1 The factors of 9 are 1, 3, and 9. The factors of 21 are 1, 3, 7, and 21. The common factors are 1 and 3; the least (smallest) common factor is 1.
What is the least common factors of 4 and 50?
The least common factor of any set of positive integers is 1.
What are the least common factors for 21 and 63?
The least common factor of any set of positive integers is 1.
What is the least common factor of 26 and 39?
The least common factor of any set of numbers is 1. The factors of 26 are 1, 2, 13, and 26. The factors of 39 are 1, 3, 13, and 39. The common factors of 26 and 39 are 1 and 13. Therefore, the least common factor (the smallest common factor) is 1.
